ClassCastException from doFilter

Hi,
I added a security filter in front of Weblogic 8.1 WebServiceServlet and at the
end of my filter, I passed a customized HttpServletRequestwrapper instance to
the doFilter(req, resp) call. I am getting a ClassCastException as following:
Error 500--Internal Server Error

Does any one have this same problem before? Where can I find the source code for
this WebServiceServlet?
Many thanks and best regards,

Hi Jacky,
Take a look at the servlet example posted by Michael [1] and see if this
answers your question.
Hope this helps,

ClassCastException from OraclePreparedStatement.setArrayInternal() method

The following code throws a ClassCastException from oracle.jdbc.driver.OraclePreparedStatement.setArrayInternal() method line# 5886 when cs.setArray() is executed.
Connection conn = getConnection(); // Returns a java.sql.Connection instance
CallableStatement cs = conn.prepareCall(queryString);
cs.setArray(1, new UsnArray(usns)); // UsnArray implements java.sql.Array
cs.registerOutParameter(2, Types.INTEGER);
cs.execute();
This works if I create the CallableStatement on an oracle.jdbc.driver.OracleConnection instance and use an oracle.sql.ARRAY instance in the setArray() method call. A JDBC-compliance driver shouldn't be expecting the applications to use driver-specific classes. The application can pass any instance of type java.sql.Array in the setArray() method call.
Is this a bug in the driver?
Driver information from ojdbc14.jar manifest.mf file:
Manifest-Version: 1.0

--------------------------------------------------------------------------------------------------

Let me elaborate on your last two replies: it doesn't matter what other drivers support; it doesn't matter what your "intention" was; all that matters is whether the implementation adheres to the specification or not. If it is not, it is not compliant to the specification (period). It is a very strong statement to say that "You must use oracle.sql.ARRAY." I'm not quite sure you understand the meaning and motivation behind standards like JDBC and J2EE and standards bodies like ANSI. This is very obvious when you say that "This is a limitation of the expressiveness of the Java type system."
If you think the JDBC compliance only mandates that "A driver is only required to accept a value that is of the concrete class defined by the driver," which is not mentioned anywhere in the spec anyway, then Sun would have simply defined the setArray method as "public void setArray(int i, oracle.sql.ARRAY x)" (one for each driver available) instead of saying "public void setArray(int i, java.sql.Array x)". It also clearly says that if a specification is not supported by a driver, in which case it must be specified in the DatabaseMetaData, the driver must throw a SQLEception. Bur your claim completely contradicts everything. You can also refer links like this on the Web: http://archives.postgresql.org/pgsql-jdbc/2003-07/msg00294.php.
I don't know what you mean by "The JDBC spec is not as precise as it could be." The relevant requirements have been clearly stated throughout Chapter 13 “Statements” and in Appendix B "Data Type Conversion Tables" in JDBC 3.0 spec (Chapter 8 Section 3 "Arrays" in JDBC 2.1 spec).
A JDBC driver may provide underlying data source-specific features in addition to those mandated by the JDBC specification. Applications that try to take advantage these additional features may decide to “stick” with a specific driver and import driver-specific classes. But these additional features cannot substitute the basic requirements.

ClassCastException from LDControl

Hi,
I am trying to invoke a LD Query using LDControl from a pageflow.
I keep getting java.lang.ClassCastException on method call to myControl.LDQueryMethod().
My guess is that its some data-type mismatch between the schema returned by the LD Query and the auto-generated XML Bean.
Is there any way to debug where this exception is coming from?

How to catch ClassCastException from JSP page?

I get a ClassCastException within my JSP page and I know where my bug is. However, this classcastexception message is displayed in the browser and I want to catch this exception to also log it into my log file. But I can't find the place where to catch it: in my servlet's doPost() method I can't catch it - i tried it by enclosing the method body with try/catch but it isn't catched. I wonder if I can catch it at all or if this error is handled internally in the servlet engine?

It should only be displayed in the browser if you're not catching the exception in the jsp itself. If the exception is happening in the jsp, then there's no point in trying to catch it in the servlet.
What happens if you put a try-catch just around the actual code in the jsp? You could put it around the entire jsp, but that's not necessary.
One problem I've encountered in catching exceptions is if there are escape sequences within the try block, for example:
try{
//java code
%>

<%
//java
catch (Exception e)I'm not sure if that works or not, but to be safe, make sure you're not escaping from jsp within the try block.

ClassCastException from appendSecondaryDocument( non-oracle-generated-XMLDocument i )

I wrote an xsql custom handler that converts html to xhtml and includes it into my xsql-generated xml.
It gets slow because appendSecondaryDocument() throws a ClassCastException if I pass in a (XML) Document that is generated by the parser in JTidy.
I therefore have to reparse this document using Oracle parser, which degrades performance too much.
Is there any way to avoid this reparsing?
I included code that shows the problem, the code relies on the JTidy library, which may be downloaded from:
http://sourceforge.net/projects/jtidy/

Looks like you already figure this one out, but basically the XSQL Page Processor expects the DOM implementation that is used to be the fast Oracle DOM implementation for performance reasons.

Sun 8: ClassCastException from ManagementHome

I am trying to use JMX from Sun 8 using a java application client.
When I tried:
Context ctx = new InitialContext(properties);
Object objref = ctx.lookup("ejb/mgmt/MEJB");
ManagementHome home = (ManagementHome)
PortableRemoteObject.narrow(objref, ManagementHome.class);
I got error:
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java
:293)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
What is missing from my program or environment?
My classpath is: .;d:\sun\appserver\lib\j2ee.jar;d:\sun\appserver\lib\appserv-rt.jar;d:\sun\appserver\lib\appserv-admin.jar
My java -version is:
java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)
Any information would be appreciated. Thanks in advance.

Hi Hans,
Thanks for your advice: I set these three properties now. I can go one step futher.
Now I can get ManagementHome object without errors. But when I tried to call create(),
I got error below. What else do I miss?

Argh; it's a bug. It'll only happen when the data cache is enabled, by
the way. Darn... you'll have to make due with casting to
kodo.query.KodoQuery.
Was there a specific JDBCQuery method you needed to invoke?Yes... setJoinSyntax().

Problem with app migration from JDeveloper 11.1.1.0 to JDeveloper 11.1.1.2

Hi Fusion developers,
I'm migrating an application to JDeveloper 11.1.1.2 from JDeveloper 11.1.1.0 environment.
I've installed the JDeveloper 11.1.1.2 Studio package on a new laptop with Windows XP Pro service pack 3
and copied the application from a JDeveloper 11.1.1.0 environment. I opened the application with JDev 11.1.1.2
and JDev converted the application.
When I run the application, I received a ClassCastException from MyFaces Trinidad. I've pasted the stacktrace
below.
I checked the 11.1.1.2 release notes and didn't find any Trinidad issues. Does 11.1.1.2 use a different Trinidad
release? If so, are there Trinidad config settings that I should modify?
Thanks,
Bob

HELP!! ClassCastException with custom module classloader hierarchy and redeployment

Hi,
I am defining custom module classloader hierarchy to avoid redeploying of the
entire application mainly because we have so many EJBs and it takes a long time
to deploy the entire app. I deploy my app using the exploded directory, add a
new method to an EJB in my dal.jar, redeploy, run my unittest and I get ClassCastException.
I am using weblogic.Deployer utility to reploy my module using "-targets dal.jar@accsserver"
argument. I even tried undeploying that module and redeploy again with no luck.
here is weblogic-application.xml definition of the custom class loader
<classloader-structure>
<module-ref>
     <module-uri>floghmi.war</module-uri>
     </module-ref>
<module-ref>
     <module-uri>cts.jar</module-uri>
     </module-ref>
<module-ref>
     <module-uri>fdbs.jar</module-uri>
     </module-ref>
<classloader-structure>
     <module-ref>
          <module-uri>dml.jar</module-uri>
     </module-ref>
<classloader-structure>
     <module-ref>
     <module-uri>dal.jar</module-uri>
</module-ref>
</classloader-structure>
</classloader-structure>
</classloader-structure>
thanks,
Nasrin

Rob,
regarding your question on redeploying the whole app without the classloader
structure, yes, that works fine. If I change a class and redeploy the whole app,
things are ok. However, when I speocify the classloader structure, and try to
redeploy the dal.jar, I get ClassClasException.
You are right about dml.jar being in a separate classloader. I have changed my
structure after I posted my question to load dml.jar from the application classloader.
So Rob, is there a bug in Weblogic 8.1 that causes this exception?
please let me know, I am anxiously waiting your response.
thanks,
Nasrin

Rob,
if I remove my classloader structure from weblogic-application.xml,I get an
error during redeployment, saying "You must include all of<list ofmy module names
here> in your files list to modify <dal.jar>. Yes, the server enforces constraints on partial redeployments. You must
deploy all the modules in a given classloader and any modules in child
classloaders.
Just to make sure, if you initially deploy your app, or redeploy the
whole thing, it works fine without the classloader-structure, right?
The problem I am trying to solve is to minimize our deployment time.Our application
has over 700 CMP 2.0 entity beans and 200 session beans. Our applicationdeployment
follows the J2EE layer architecture. The data mapping layer which consistof 700
entity beans are located in dml.jar. The data access layer which consistof 200
session beans are located in dal.jar. We create our ear with thesetwo jar files
plus some other framework jars and deploy on bea weblogic 8.1 SP2 andthat takes
about an hour. I need to be able to modify a session bean, i.e. changethe implementation
of a session bean or add a new method to a session bean interface andredeploy
only data access layer, the dal.jar, not the entity beans. This explainswhy you
see dml.jar in a classloader with a child classloader that loads dal.jar.
I included the ClassCastException from weblogic server console below.What is
happening is that I have a session bean with 6 methods that just doesa println.
I deploy my session bean, ExerciseSessionBeanFactory, and run my unittest that
invokes test1 through test6 methods. I modify my bean to add "test7"method and
redeply dal.jar successfully. I run my unit test that invokes test1through test7
methods and then I get a ClassCastException.
I hope this helps. Please let me know if you need more details.If you push dml.jar into a subloader, that means you can change dml.jar
without touching anything in the parent loader. However, it also means
that you've isolated it's classes and other modules can't see them.

Workshop 8.1 Calling EJB from Custom Authentication Provider

I am writing a custom authentication provider that runs on Weblogic Server 8.1 and also on Workshop 8.1. Everything is packaged into a jar file that I put into the mbeantypes directory. From the authentication provider I want to get an EJB home that is on another Weblogic 8.1 server.
Loading the home from the Weblogic server works great. But in Workshop I get a ClassCastException from the PortableRemoteObject.narrow() call.
This happens in Workshop even if I remove all my application jar files, so I am left with nothing but the startup classpath and the files in the mbeantypes directory. That is, I don't have any classes in two directories.
When I look at the class that I actually get back from the call to context.lookup( jndiName ), I get the same stub class back on the Weblogic Server and on the Workshop server. But only on Workshop do I have this casting problem.
Any ideas?
Thanks,
Mark

Issue has been resolved.
The reason I've forgotten about Value Object that is being returned by Remoute method to put them into classpath of Authenticator Provider

ClassCastException under 7.2

I'm porting an application that works under LCRE 7.0.2 to LCRE 7.2 and I've started getting ClassCastExceptions from the last line in the following code:
// Lookup the PDF Manipulation service
Object pdfObject = namingContext.lookup("PDFManipulation");
pdfConnectionFactory = (ConnectionFactory) PortableRemoteObject.narrow(pdfObject, ConnectionFactory.class);
The code is straight out of the documentation. What's strange is that I've already successfully retrieved a connection to the DataManagerService a few lines before.
Has anyone else encountered this before? I basically re-built the project from scratch copying over my old java source files to the new project and then copied in the new .jar files from 7.2.
The only thing that strikes me as odd is that under 7.0.2 I had to refer to DocumentServicesLibrary.jar as an external file (since, under 7.0.2 it was copied into JBoss's lib directory) and under 7.2 I'm including it in the .war (per the LC Forms documentation, the LC RE docs don't say much about DocumentServicesLibrary.jar). This library is the one that contains the ConnectionFactory class that the narrow() call is unable to cast to. Perhaps it's a coincidence, but I'm thinking that it's related.
Should the DocumentServicesLibrary really be included in my .war file or should it be excluded as it was under 7.2? I've tried it both ways but neither works.

Rob McDougall
4 Point Solutions

Hi Chris,
That did the trick. Thanks!
The knowledgebase article should probably be amended to mention Reader Extensions (I hadn't installed Document Security, yet I still encountered the problem). It would also be nice if it gave the exact exception that is generated (a ClassCastException). I had searched the knowledgebase for both ClassCastException and Exception although I limited my search to Reader Extensions, so I didn't end up finding that article.
Thanks again for pointing it out.
Regards,
Rob

J2SDK 1.3 on Linux RH 7.1

Hi... does anyone can give a hand installing J2SDK 1.3. on Linux RH 7.1?
I've already installed Java using the rpm file and it seems to have no problems...
everything looks fine...I've got no error messages...
but when I try to run: java -version
there is not answer!..just nothing!
this is the second installation and I don't know what else to do...
what I'm missing?
I hope anyone can help me!
Thanks in advance!
ciao!

Resource Adapter errors in WebLogic 10.3

Hi,
I'm getting ClassCastException from coherence 3.5.3 resource adapter in WebLogic 10.3.
I've already tried to install resource adapter as a separate deploy and inside ear file, but get same errors.
Has anybody already managed to use this adapter along with weblogic 10.3 ? The error occurs when I try to get a NamedCache object. The distributed cache named "cache" is up and running since I manage to get and put objects into cache by using NamedCache from CacheFactory (CacheFactory.getCache("cache")).
               ctx = new InitialContext();
               // the transaction manager from container
               tx = (UserTransaction) ctx.lookup("java:comp/UserTransaction");
               tx.begin();
               adapter = new CacheAdapter(ctx, "tangosol.coherenceTx", CacheAdapter.CONCUR_PESSIMISTIC ,CacheAdapter.TRANSACTION_REPEATABLE_GET, 300);
               NamedCache cache = adapter.getNamedCache("cache", getClass().getClassLoader());
               cache.put(1, 11);
               Integer estoqueGet = (Integer)cache.get(1);

The problem may be related to having more than one coherence.jar and tangosol.jar in the classpath. Can you verify that you only have one of those in the classpath?

JPA Toplink, class cast exception when casting class A to class A

I get a really strange exception from Toplink JPA. I used netbeans to create a persistence.xml and I generated a class (entity) from the table in a DB. Everything works fine, when I create a select query, I get the list of objects and the list is correctly typed. I can the objects in the list in debug mode with every field correctly set. But then I need to start working with the list, so I iterate through the list. And then I get ClassCastException from class A to class A (when A is the canonical name of the entity class).
I was working with JPA for some time but never seen that. I am using glassfish v2, mysql, netbeans 6.1. I could post the classes and persistence xml, but persistence.xml is really simple (no class definitions) and the class is annotated by netbeans. Every field is annotated like this:
@Column(name = "name", nullable = false)
And Date columns have
@Temporal(TemporalType.TIMESTAMP)
The whole class is annotated with @Table.
Does anyone has any idea, what can be wrong?

Make sure your URLClassLoader cannot load the IAdapter class.
That is not exactly correct. He needs to make sure his URLClassloader has access to the IAdapter class. Sure, it should not load it on its own, but if requested the URLClassloader should be able to ask a parent to load IAdapter. Which in the end looks the same. But is not the same.
So set the parent classloader of your URLClassloader to a classloader capable of loading IAdapter.
